First of all, is the Developer still around to even support the game? I've been looking everywhere to buy the DLC as I have the Pre-Order Edition of Crysis 2.

However, sadly as it is, there is only a pinned topic which says that sale of DLC is not available "for the time being" which seems indefinitely.

Crytek seem to have abandon the entire Crysis 2 on PC platform and release the Maximum Edition (seems to be the ONLY way to get the DLC and I need to fork out for the full game the second time) to salvage whatever they can and move on to Crysis 3 (it's the only thing they advertise or care now).

I remember the CEO/Director guy of Crytek said sometime ago that they might abandon the PC platform due to piracy. With this kind of support and marketing strategy I'd say go screw the console players instead!
